Anti-PD-1 treatment as a neurotherapy to enhance neuronal excitability, synaptic plasticity and memory

Show abstract
Emerging immunotherapy using anti-PD-1 antibodies have improved survival in cancer patients by immune activation. Here we show that functional PD-1 receptor is present in hippocampal CA1 neurons and loss of PD-1 or local anti-PD-1 treatment with nivolumab enhances neuronal excitability and long-term potentiation in CA1 neurons, leading to enhanced learning and memory. Our findings suggest that anti-PD-1 antibody also acts as a neurotherapy for improving memory and counteracting cognitive decline.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
